Hi I'm Sarah,
I've just read your diary and I'm a party girl like you, I love going out and getting pi**ed up, but since starting sw I've noticed if I drink at the weekend I end up at the kebab shop, then I do rubbish at weigh in, so im trying to not drink unless it's a special occasion because I can't just have a few, I don't know where to stop.
I log my food & exercise on mfp too, I know sw isn't about counting cals but I like the extra support & it's free, what's your username on there and I will add you if you don't mind?
